This invention relates to improvements in window sash mountings, and has for an outstanding object the provision of a sash mounting in which both the top and bottom sashes of the window are counterbalanced and i sashes.

Itis a difiicult and often physically dangerous task to wash the exterior surfaces of ordinary window sashes and constitutes a source of considerable expense especially in the upi keep of public or semi-public buildings. Itis customary to employ experienced operators for the speciiic purpose of periodically cleaning the windows. A large part of this eX- pense may be attributed to the difficulty encountered in cleaning the outer surfaces of the windows and to the hazardous character of the operation. It is, therefore, the principal purpose of the present invention to permit of the washing of the windows from positions within the building in which the windows are mounted in order to permit the work to be more thoroughly and expeditiously accomplished and, if desired, by inexpert labor with accompanying low costs.

It is another object of the invention to provide a sash mounting wherein provision is made for locking the sashes ina horizontal plane when the latter are swung inwardly to admit of their cleansing, the locking being accomplished automatically through swinging movement of the sash or sashes in order to avoid the necessity of manually holding the sashes in a fixed position during thev cleansing operation.

A further object of the invention resides in the provision of means for weather stripping the various relatively movable members comprising the sash mounting in order that the construction would be weather-tight and secure againstrattle and vibration.

V,taken on the It is Stm a uthe blCt of the invention i* i to provide means in connection with ithe mounting whereby lthe sashes lmay assume partially open or inclined positions withrespect` to the vertical, in order `to admit of proper and adequate ventilation of the rooms without creating undesired drafts.

It is anotherV objectief the invention to pro-v vide means for locking the 'sashes in their partially open or Ventilating positions.

The invention also has for further general objects the provision of` a sash rmountingfof simple, light weight and "durable construction which is not apt to become outof order or to require undue attentionfor` adjustment to maintain the same in proper working order, the mounting possessing substantially the simplicity and freedom from repairas is present in window constructions of conven-v tional design but with, ofcourse, the above added features of advantage.

With these and other objects in view, which will appear as the description proceeds, the invention consists in the novel `features of construction, combinationsof elements and arrangements of parts hereinafter to be more fully described and pointed out 'in' the appended claims. L

Referringl more particularly tothe ings, the numeral 1 desginates the frame structure of the window. This frame lstructure may be substantially conventional in deV sign and `isprovidedwith the usual sill or ledge 2, vertical side walls 3-3 and a top silll 4,*which are shaped and positioned to produce the usual rectangular opening for the reception of vthe vertically slidable upper and lower window sashes 5 and 6 respectively. The side walls 3 are provided with transversely spaced vertically extending guides 7 which form channels 8 vin vconnection with whichv the sashes Vare guided for sliding movement in verticalplanes. Y

To effect the mounting of the sashes insuch manner that the latter, in addition tothe customary vertically sliding movement, may. Abe swung inwardly and rocked about horizontal axes,'the present invention provides a mounting foreach sash which includes a pair of vertically disposed channel members 9.

These members kare arranged to occupy the vertical guide channels 8 and to slidefvertically therein. The channel members are preferably formed from alight weight metal such as an alloy of aluminum and in the ,pres-Y ent instance each of said members 'consists of a pair ofsections 10 and 11 provided with fiat adjoining faces 12 and 13 which are spot welded or otherwise rigidly secured together i to produce a rigid rassembly Vof necessary 'mechanicalfstrength and yet of unusual crosssectionalformation. The sections 10 and 11 include vertically extending, transversely v spaced walls 14 adapted'toengage with the sion vof vertical weather strips 16. These strips are directly secured to the side walls 3 and have their free or resilient vertical edges f swinging movementof the sashes about hori-V Zontal axes. To effect the pivotal mounting of the sashes cach of the latter has secured thereto along the full length ofits vertical side edges substantially flat metallic strips 17 which, when the sashes are in vertical planes, engage closely with the walls Y12 of the channel members 9. The lower ends of the. strips 17 have welded or otherwise rigidly se-` cured thereto, a pair Yof trunnion studs V18 for each sash. These studs have been Shown particularly in Figures 6, 7 and 13. Each stud is formed to include an enlarged circular iead 19 from which projects a cylindrical shank 20. This shanky terminates in a non circular portion 21 and in a diametrically re-V duced extension 22. The non-circular portion 2l is shaped to be positioned within a correspondingly formed opening formed in a cam element 28, while the extension 22 is received within a small circular opening formed centrally ina clamping plate 24. This plate. as shown in Figure 13 especially and also in Figures 6 and v7, is provided withcam sur'- faces-25 and with vertical locking shoulders 26, while the element 23 includes laterally turned lips 27 having cam edges 28.

By virtue of this construction it will be seen that when the sashes are swung inward-l ly about the horizontalaxes provided by the shanks 20 of-the studs 18, the strips 17 move in unison therewith, since said strips are directly secured to the-side edges of the window sashes. Then, since the studs 18 are rigidly secured orif desired, integrally formed with the strips 17 the said studs revolve about their longitudinalr axes. This results in the rotation of? the cam elements 23 since thelatter are mountedfon the non-circular portions 21 of the stud Shanks 20. The rotation of the cam elements 28 bring the lips 27 thereof into Vengagement with the cam surfaces 25 of the locking plate 24, forcing saidk vplates outwardly against the resistance exercised thereon by the springs 29 which are carried by the extreme outer ends of the studs 18.V This results in bringing the rubber .bearing surfaces 30provided on the plates 24 into frictional contact with the-flanges 15 of the channel members 9 or the weather strip 16', as shown in Fig-ure 6, with the result that when the sashes 5 and assume substantially hori imanes zontal positions they are frictionally locked against upward movement, since the plates 24 press the flanges 15 of the channel membersV 9 into 'firm frictional contact with the side walls 38, creating such friction as to overcome the iniiuence of the sash weights 31 on, the channel members).

It will be understood that when the saslies are moved to a horizontal position theload which they exercise normally on the weights 31 is lessened. This would result in the ele` Vvation vofV the sashes when the latter assume horizontal positions if the frictional locks were not provided. However, by the inclusion of the 1locks it will be seen that when the sashes are moved to horizontal or other positions decreasing the load on the weights 31 vertical movement of the sashes in respense to the influence of the counterbalancing weights is precluded through the employmentof the frictional locking mechanism described. VThe channel members 9, as shown in Figures V4 and 5, are provided with integral tongues 32 which are-receivedl within eyes`33 Vformed in connectionwith' cable ann chors' 34. The cables 35 are suitably connect'- ed with the anchors 34 and are trained over the usual pulleys in the upper portion of the frame structure and have their lower free `ends connected with thefsash Weights 31which function in the usual manner to counterbal'ance the weight of the sa'shes 5 and 6 when' the latter ai'e moved in. normal vertical planes.

In addition to the inward swinging'movement imparted to the sashes for the purpose of facilitating cleaning thereof or other delsired operations, the Vpresent invention further admits of the positioning of said sashes so that the latter may be effectively employed for4 the purpose of room ventilation. In this respect each of the sashes is capable ofl swinging about the axis provided by the studs 18 to a'limited extent' so as to be angularly positioned withresp'ect tothe vertical. This permits air to enter a room in an upward 'direction toward the ceiling, prevents ing the creation of objectionable drafts and other air currents in the room.

To retain the sashes in said positions of partial opening for ventilation use ismade of the structure depicted in detail in Figures 9 to 12 inclusive. The section 11 of each of the channel members has its `wall or Vface 13 provided with a vertical recess or groove 36 which is employed to receive a pin 37 carried by the upper end of a link 38. There are, of course, two of these links for each sash, th-e lower ends Yof said links being pivotally connected, as at 39, with the sash strips 17. Secured to the rear or inner surface of the walls 13'of eac-h section 11 is a spring lock 40 illustrated in detailv in ligure 12. This lock includes an enlarged base 41 which is riveted or otherwise fastened to the wall 13 and the base 41 terminatesin a forwardly directed i resilient arm 42. This arm` projects into the groove 36and is provided-vatthis point i the customary turnlatch 45, which locks the f sashes, is opened. -This permits the lower Sash to rock about its horizontal axis in'an inwardV d-irection. Following a. predeter-l mined degree' of'oscillation on the part of the sash the pins 37 provided-on the links V38- are moved downwardly in the grooves 36 until they contact with theupper of the. resilient fingers 43. Slight further movement results in Vresilientlv operating the arm 42 so that the pins 37 will be positioned between the locking shoulders 44. In this manner 4the sashes are heldlocked or secured in" their Ventilating positions and cannot vlbe furthen` moved unt-il the -fingers 43 Vare manually `moved 4inwardly by operating the exteriorly projecting portions of the arm '742. ,'Wh'en this is done the sash may be moved about its horizontal axis either'to a positionvof clo sure or toa position more fully opening the window. One or more of the catches 40 may be provided Jin connection with .each sash in order to secure a variety of full or partially opened positions. V n

Tn view ofthe foregoing it will be seen that the present invention-providesal window sashmountingof simple, readily operatedand practical design for attainingthe objects of the invention and the features of construction which T have abovepointedout.

In summer' tlieinvention arovidesiirst for the' inward swinging movement of a window sash about a substantially horizontal axis forV the purpose of facilitating the cleaningr ofthe glass panel or panels of the sash, permitting this rwork to be accomplished from within a room and without dangerl ordis- Y comfort to the operator. Seco-nd, the invention provides for the provision of automatically'operating means forpreventing ver` tical slantingr'movement of the sash when the latte-r `is being` rocked about its horizon-4 tal axis toits full opened or extended position within the room. This permits of the usey of the ordinary counterbalancing weights for` ordinary raising and loweringl of the window in vertical planesv and yetpro-V vides'for the turning of the sashl about its horizontal axis and the removal of the effec- .and

as to permit ofthe positioning of the sash in partially opened or turned positions about said horizontal axis irl-order to providefor" Y room ventilation and the locking of thesash Y in 'such positions Vof partial opening.; f Furl.
